After thwarting the violent international fascist syndicate known as Nemesis, Evan Ryder returns to Washington, D.C., only to find her secret division of the Department of Defense shut down and her deceased sister's children missing. Now the target of a cabal of American billionaires who were among Nemesis's supporters, Evan and her former boss, Ben Butler, must learn to work together as partners – and navigate their intricate past – as they hunt down her family's kidnappers.

Their search will take them from Istanbul to Odessa to an ancient church deep within the Carpathian Mountains of Romania. And all along the way, an unimaginable enemy stalks in the shadows, an adversary whose secretive past will upend Evan's entire world, and might just annihilate her.

Thoroughly enjoyed the first Evan Ryder Book - The Nemesis Manifesto. Book one perfectly set up the scene for The Kobalt Dossier. These are complex narratives, tightly written nd requite full concentration! Evans is a likeable (to me anyway!) and believable agent. There are lots of double agents which means (for me) it's sometimes hard to follow who is who and how they know one another. Nonetheless it was an enjoyable read.

An excellent spy and action story which is full of multiple plot lines gradually intertwining, characters with various agendas, cross, double cross and triple cross and keeping you guessing all the way through. The action is constant and occurring in different locations, never clear who is pulling what strings. As always with a good book, you look forward to seeing where the characters go next in the future books.

I loved everything about this book. Eric Van Lustbader has done a magnificent job with a well thought out and tense story. Besides having an interesting plot, it’s the characters that really make this a wonderful book. Evan is definitely my favourite, she’s absolutely relentless.
Ben and Evan didn’t expect there to be any repercussions when they dismantled Nemisis, however they soon found out how upset they had made some powerful people. It was no coincidence when Evan’s niece and nephew go missing. Evan is keen to track them down by herself, however Ben wasn’t going to let her do this by herself, especially after an attempt was made on her life. Even worse was when Evan was told that her sister had been a spy for the Russians, which she thought had to be disinformation, I mean why would her sister do such a thing?
If you enjoy Thrillers, then you will love this book. It’s well worth a read. 5/5 Star Rating.
